推荐答案

这是一般的解决方案，但我不知道您要实现什么，因此请根据您的需要进行修改

Hi,

This is the general solution, but I don''t know what you want to achieve, so modify this according to your needs

private ArrayList GetCheckedItems(string ctrl, DataGrid grid)
{
    ArrayList checkedItems = new ArrayList();
    CheckBox chk;
    string strID = string.Empty;
	
    // Loop through each row in the GridView
    foreach(DataGridItem item in grid.Items)
    {
        chk = (CheckBox)item.Cells[0].Controls[1];

        strID = grid.DataKeys[item.ItemIndex].ToString();

        // Now see if the current CheckBox is checked
        if (chk.Checked)
        {
            // See if the current value is in the list, if not add it
            if (!(checkedItems.Contains(strID)))
            {
                checkedItems.Add(strID);
            }
        }
    }
	
	return checkedItems;
}
